Dc Posted January 24, 2007 Share Posted January 24, 2007 Our tank is in a very cold part of the house is it worth lagging the tank to keep the water hotter or would I be wasting my time. Any advice greatly appreciated.regardsdc Link to comment Share on other sites More sharing options...

Any advice greatly appreciated.regardsdc [/quote]Tank itself won't need lagging unless it is very old; Most French chauffe eaus have a polystyrene insulation between inner and outer metal skin and problems will only occur when the tank is left cold and unused , whereby draining down is the better option. It would be worth lagging the pipes of course where they enter/exit the C/E. Link to comment Share on other sites More sharing options...
Albert the InfoGipsy Posted January 24, 2007 Share Posted January 24, 2007 When you know it's full of hot water just feel the top of the tank. If it feels warm or hot then it may be worth adding extra insulation, otherwise it's a waste of money and effort. Link to comment Share on other sites More sharing options...
saddie Posted January 24, 2007 Share Posted January 24, 2007 I haven't come across a ballon where you could feel any escaping heat. I believe that they are glass lined and certainly are very effective. When you consider the imersion heaters in England and the lagging ! Incredibly inefficient Link to comment Share on other sites More sharing options...
Tresco Posted January 24, 2007 Share Posted January 24, 2007 I agree with Albert and saddie.We had a French visitor in England not long before we came here, and he was intrigued then delighted by the lagging on our tank. He used a word which I think meant 'quaint' which was generous, if you think about it.[:)] Link to comment Share on other sites More sharing options...
Chancer Posted January 25, 2007 Share Posted January 25, 2007 I disc cut one in half to remove it easier, what I found inside was very interesting:Outer skin thin guage electropainted steel, insulation layer some kind of vermiculite granules, inner skin 1/4" welded steel, then finally about as much calcium carbonate inside as insulation outside - I live in a very chalky area.The inner pressuer vessel had corroded through and there was evidence of rust staining around the grope de securite, I would reccomend that people keep an eye out for this as by then the inner insulation will be sodden.I fitted a French ballon to a flat in England, despite being very small and having less mass effect than the larger ones it kept most of its heat for 5 days after use so they are very well insulated.I have also had French visitors laugh when seeing a UK cylinder.My biggest laugh was when I showed a rich friend the prices of French ballons, he had previously paid £2000 during a renovation to have " a wonderful new pressurised system", he did not share my pleasure to see that he in fact had an £80 ballon albeit with an expansion vessel!Editted: Not a good day for my spelling but i quite like some of the mistakes!

Dick Smith Posted January 25, 2007 Share Posted January 25, 2007 The grope de securite has possibilities, I think...I have always been amazed at how cool the outside of the ballon is compared to our 'insulated' hot water tank in the UK. I wonder how that runs out in extra costs. Link to comment Share on other sites More sharing options...
